I've just found that my mate is using the fully comp insurance for a car he NO LONGER OWNS to drive ALL his friends cars!! He's a barman and after work he drives regulars home if they've drunk too much for a bit of cash. When i questioned him he said he still has 9 months left on an insurance policy for a peugeot 306 1.6 diesel he has scrapped and that this allows him to drive any other car with the drivers permission. I'm sure this is totally illegal, or am i mad? Even if you had a valid insurance policy for a shi**y 1.6 diesel it wouldn't cover you to drive a more powerful or expensive car would it? Should i tell the people who let him drive their cars what they're risking?
